#Agricultural Technology Science Popularization Contest Season 2 # Recently I heard that some fruit farmers in the village have sprayed Naphthaleneacetic acid on Wang Lin apples. Because Wang Lin apples have fruit drops before harvesting, over the years, fruit farmers have sprayed naphthaleneacetic acid to prevent fruit fall before harvest.
This afternoon, I also went to the agricultural material store to buy a bottle of naphthalene acetic acid, sprayed the seven Wang Lin apple trees once, and sprayed it a second time after half a month.
In fact, Wang Lin apples fall fruit before harvesting, not very serious, the main reason is that the harvest is late, the second is that there are bitter pox disease, mold heart disease, or insect eyes on the fruit, and the most fruit fallen is this kind of disease residue fruit.
